Which country has the highest energy storage capacity in the world?

From the perspective of publication volume in different economies, China far exceeds the United States, Japan, and Europe in the field of EST, mainly concentrated in electrochemical energy storage and electromagnetic energy storage.

When was energy storage invented?

The earliest gravity-based pumped storage system was developed in Switzerland in 1907 and has since been widely applied globally. However, from an industry perspective, energy storage is still in its early stages of development. With the large-scale generation of RE, energy storage technologies have become increasingly important.

Which countries have a literature search for energy storage technologies?

In this section, relevant literature on energy storage technologies was searched for China, the United States, Japan, and European economies. The specific numbers of collected literature are shown in Table A1. Table A1. Number of literature searches in the field of EST.

Does China have a large-scale energy storage technology?

China has included large-scale energy storage technology in the National Energy Plan during the 12th Five-Year Plan Period and has been actively guiding and promoting the development of the energy storage industry. 1.3. Demands and functions of energy storage technology in power systems 1.3.1.

How do governments promote the development of energy storage?

To promote the development of energy storage, various governments have successively introduced a series of policy measures. Since 2009, the United States has enacted relevant policies to support and promote the research and demonstration application of energy storage.

Why is energy storage important?

With the large-scale generation of RE, energy storage technologies have become increasingly important. Any energy storage deployed in the five subsystems of the power system (generation, transmission, substations, distribution, and consumption) can help balance the supply and demand of electricity .
